Strawberry plant named &#39;DrisStrawFortyFour&#39;

ABSTRACT

A new and distinct variety of strawberry plant named ‘DrisStrawFortyFour’ particularly characterized by medium red strongly glossy fruit, early harvest maturity and moderate resistance to powdery mildew, is disclosed.

GENUS AND SPECIES

Fragaria×ananassa

VARIETY DENOMINATION

‘DrisStrawFortyFour’

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry variety designated ‘DrisStrawFortyFour’ and botanically known as Fragaria×ananassa. This new strawberry variety was discovered in Monterey County, California in October 2009 and originated from a cross between proprietary open pollinated bulk (unpatented) and the proprietary male parent ‘112N245’ (unpatented). A single plant was selected and asexually propagated via tissue culture and vegetative cuttings in Shasta County, California.

‘DrisStrawFortyFour’ underwent further testing in Monterey County, California for five years (2009-2014). The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons and tissue culture.

Plant Breeder's Rights for this variety have not been applied for. ‘DrisStrawFortyFour’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Monterey County, California.

1. Medium red, strongly glossy fruit;

2. Early harvest maturity; and

3. Moderate resistance to powdery mildew.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the new variety at various stages of development. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken from nine-month-old plants.

FIG. 1 shows upper and lower surfaces of the leaves of the plant with three leaflets.

FIG. 2 shows both upper and lower surfaces of the flowers.

FIG. 3 shows the whole fruit.

FIG. 4 shows the fruit in longitudinal cross-section.

FIG. 5 shows the whole plant.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawFortyFour’. The data which define these characteristics is based on observations taken in Monterey County, California from 2009 to 2014. This description is in accordance with UPOV terminology. Color designations, color descriptions, and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic, and cultural conditions. ‘DrisStrawFortyFour’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawFortyFour’ was taken from nine-month-old plants. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2007 edition). Descriptive terminology follows the Plant Identification Terminology, An Illustrated Glossary, r^(d) edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

When ‘DrisStrawFortyFour’ is compared to the open pollinated bulk (unpatented), the open pollinated bulk was a group of uncharacterized seedlings that generally had less regular fruit shape, lighter fruit color and lighter leaf color than ‘DrisStrawFortyFour’.

When ‘DrisStrawFortyFour’ is compared to the male parent ‘112N245’ (unpatented), ‘DrisStrawFortyFour’ is a more vigorous and upright plant with higher yields and lighter colored fruit than ‘112N245’. In addition, ‘DrisStrawFortyFour’ produces more runners in the field than ‘112N245’.

When ‘DrisStrawFortyFour’ is compared to the commercial variety ‘Monterey’ (U.S. Plant Pat. No. 19,767), ‘DrisStrawFortyFour’ has a slightly concave leaf shape in cross section, dense petiole pubescence and petals with a concavo-convex base shape, whereas ‘Monterey’ has a mostly concave leaf shape in cross section, moderate to heavy petiole pubescence and petals with an attenuate base shape.

When ‘DrisStrawFortyFour’ is compared to the commercial variety ‘DrisStrawThirtyOne’ (U.S. Plant Pat. No. 24,317), ‘DrisStrawFortyFour’ has an average of six crowns per plant and a globose—semi-upright growth habit, whereas ‘DrisStrawThirtyOne’ has an average of three crowns per plant and an upright growth habit. Additionally, ‘DrisStrawFortyFour’ has fruit with strong glossiness and d medium acidity, whereas ‘DrisStrawThirtyOne’ has fruit with medium glossiness and weak acidity. 

We claim:
 1. A new and distinct variety of strawberry plant named ‘DrisStrawFortyFour’, substantially as illustrated and described herein.
